Issue changes:

I'm actually surprised nobody mentioned this sooner. The way reload sounds are played changed between FO3 and FNV, I need to analyze exactly what changed so I can update it for any FO3 weapon.

I've known about it for a while, since my last playthrough. Only recently did it start to bother me when I got The Terriable Shotgun. I will also analize the reload sounds between FONV and FO3 and let you know what I come up with.

EDIT: I don't see anything different. They're both .WAV files, they're both 512Kbps constant, they're both mono and they're both 32Khz.

I think there's a check for the perk inside the reload script that plays it at 125% speed if you have the perk.

OK I tore this apart. The problem is located in the reload animation itself. The reload sound needs to be broken down into individual sounds and the animation needs to be told to played individual sounds at specific times, instead of all at once. Editing animations goes beyond my abilities, though I SHOULD be able to rip the sound into its components.
